Line 147 to be Temporarily Shut Down for Repair
Contact :Jeff Maltbie, City Manager, City Manager    (650) 802-4228
SAN CARLOS, CA, May 8, 2015 – Late yesterday, Pacific Gas and Electric Company (PG&E) informed San Carlos City officials that the utility began the process of reducing pressure in Natural Gas Pipeline 147 so that the line could be vented and shut down later today.

Excavation and retrofit work conducted earlier this week revealed two as of yet unexplained bulges in a section of the line near Tasker Lane, already scheduled to be replaced. PG&E notified the California Public Utilities Commission (CPUC) and the City of San Carlos of the discovery within 24 hours.  City officials then made the request to have the line shut down several days earlier than had been previously planned by the utility, to expedite work scheduled for next Tuesday. Efforts to shut down the line will continue throughout the day Friday, and PG&E crews will work for up to 24 hours on Saturday replacing the defective area of pipe. In addition, changes will be made to the geometry of sections of pipe the utility's inline inspection tool had difficulty navigating in the first attempt to conduct inspections.

Mayor Ron Collins stated, "We are all pleased and relieved by PG&E’s decision to expedite the shutdown and replacement work taking place on Line 147. Our goal has been and will remain to ensure that Line 147 is inspected and improved to assure the safety of our residents and their property."

Once the replacement and retrofit work is completed later this month, the line will be repressurized and inline inspection will resume.  City officials have also called for a thorough report and review process to be presented to the City Council by PG&E regarding the nature of these defects when the investigation and testing have concluded.
